Peaches for warm climates: New varieties are solving problem of insufficient winter chilling in southern California orchards
by M. M. Winslow
| Full text HTML  | PDF  
New peach varieties requiring little winter chilling to break dormancy are solving the problem of delayed foliation in orchards in the lower elevations of southern California.

Increasing olive fruit sizes: Thinning important in lifting fruit from substandard grade into canning quality
by H. T. Hartmann, Karl W. Opitz
| Full text HTML  | PDF  
Olives of canning fruit size are of particular interest to California olive growers due to the probable 50% cut in the tariff on olive oil.

2,4-D and citrus fruit sizes: Increase of citrus fruit size primarily due to accelerated growth rate from spray treatment
by Wm. S. Stewart, H. Z. Hield
| Full text HTML  | PDF  
For the sixth successive year the grower of Valencia oranges apparently is faced with small-sized fruit in 1950— even though the size is larger than in 1949.

Male-sterile tomatoes: Unfruitful mutants offer several advantages for the production of hybrid seed
by Charles M. Rick
| Full text HTML  | PDF  
Male-sterile tomatoes offer advantages in the production of hybrid seed— from which substantially higher yields than those of parent varieties have been reported.

Oak pit scales: Control possible with emulsion-type foliage oil and toxaphene spray
by A. Earl Pritchard, Robert E. Beer
| Full text HTML  | PDF  
Oak pit scales are serious pests of oak trees in California. Terminal growth, branches, and smaller trees are often killed as a result of the feeding scales, and large trees may be weakened seriously. Experimental work indicates that oak pit scales may be controlled.

Ripe fruit rot in tomatoes: Early maturity of fruit and harvest before fall rains are factors in reducing loss
by R. G. Grogan
| Full text HTML  | PDF  
Fruit rot in the California canning tomato crop is an important problem because state standardization laws require that fruit having 5% or more rot at the time of inspection be rejected as unfit for processing.

Potato scab control: Applications of sulfur to increase soil acidity effective in reducing disease in experiments in Kern County
by John W. Oswald, David N. Wright
| Full text HTML  | PDF  
The most promising approach in the prevention of potato scab development has been to increase the acidity of the soil by the addition of sulfur.

Sweet corn: Growth and yield affected by irrigation in semiarid areas
by John H. MacGillivray
| Full text HTML  | PDF  
Growth of sweet corn is greatly affected by insufficient soil moisture, as measured by yield of marketable ears, size of plant, and dry matter produced.

Egg washing field trials: Studies indicate clean unwashed eggs are most suitable for satisfactory storage
by F. W. Lorenz
| Full text HTML  | PDF  
Washing eggs before storage is a risky business. The only safe eggs to store are clean eggs produced clean and unwashed.
